    Exactly. YOU HAVE BROKEN THE CODE!!
    What you have been told repeatedly is that it is absurd for you to worry about a harmless thing like ping (or a toot).

    Wake up and smell the coffee.



    With all due respect, I don't think that you would recognize "logic" if it bit you on the backside.....

    Unless you are simply a troll looking for a fight, you will seek out someone you trust, who understands how the net (IP traffic) works and listen as they tell you the same things that you have (failed to learn?) learned here. You claim to want to learn. Only you can do that by dropping the attitude and listening with an open mind.................

    cheers,

    AFAIK there is no way...

    Perhaps there is a way to filter the results with your firewall (if you have a good one), but I am no security expert...

    Considering that you think that this kind of traffic is someone "hacking" (I can't stomach to put the "pinging/" in front of that, implying that a ping is a hack attempt is just idiotic) your computer, you are woefully unqualified to be responsible for any kind of network logging in the first place.



    You don't have to "deal" with it. If you're not running a gnutella client you are happily dropping the packets "dealing" with none of them. And ANY good firewall will give you the ability to drop this traffic without logging it (much as you can do with all the other random traffic floating around.)

    Or you can just unplug from the net and quit bitching.



    "Victimized"??? Noone's done you any wrong, get over it already.

    You're welcome iriegirl. The unregistered person said it well, about IP addresses being "recycled". This would more likely be your case if you have recently obtained Cable Modem access.

    There are some things to note about Cable Modem access though. Because your computer will be connected to the Internet 24/7 (or at least, it is supposed to be), you become a bit easier target to malicious users.

    A software based firewall is a good start, but I'd recommend adding a hardware firewall as well. Such firewalls are usually built into "routers" (see http://www.linksys.com, which provides these products and good information about it too). They're fairly inexpensive (around $50). In addition to that, your computer will have a different type of access to the Internet, rather than direct access to the Internet.

    Even though you may not be using a home network, you can still use the router for just one PC. It'll give you some added security, and when you decide to do add an additional PC in your home, you can use both those PCs to access the Internet with a bit more ease.

    Obviously, even hardware firewalls can be comprimised, but the thing is to make it "harder", not "easier" to get into your system.

    so, even if you don't have this "Gnutella," they can just interfere with your computer just cause you are online? And do it all day?
    no wonder there is are pro and con people for this thing.

    Once you connect to the Gnutella network, you advertise your IP address to other Gnutella clients. Those Gnutella clients will forward it to others upon request. This is how others you might have never connected to before are able to connect to you now.

    When you disconnect from the Gnutella network, your IP address will still "float" around among other Gnutella client. They are held in a cache. These caches do expire after a certain amount of time, so they won't hold your IP address forever. For some, it's just a few minutes, for others, it may be a few days.

    The issue here, is when your IP address is about to expire at one Gnutella client (say, it only has 10 seconds left to live), but another client requests more IP addresses, your IP address will now be in another one's cache, who may again store it for another period of time as a "fresh" IP address. And so on, and so on. So it may take a while before your IP address is completely out of the Gnutella network.

    But for that reason, you will keep receiving incoming Gnutella connect requests, which may appear as "pings" in ZoneAlarm or other firewalls, because your client's isn't up and running (thus the system needs to report it as "closed", or in your case, filter the request out). That may appear as a hack attempt, while in fact it is not.

    Now, this isn't something considered high-priority for most developers to solve. However, with the intruduction of some new extension within Gnutella itself, a proposal might come forth that adds a "freshness" or "age" tag to your IP address, so it can be removed from the network if it is getting "old" - ensuring it will be removed faster than currently done.

    There are two possibilities:

    First you disconneted short time ago. Your IP is still in the caches and the people try to connect!

    Or somebody tries to resume his download, do you have a fixed IP or dynamic? If you have a dynamic one did it change after you disconneted?

    Yes I thought the same way but the funny thing is that iriegirl never installed a Gnutella client...
